Answer:
Las cargas eléctricas de los objetos son ambas positivas o son ambas negativas.
Explanation:
Si dos objetos presentan fuerzas eléctricas repulsivas entre sí, quiere decir que ambos tienen el mismo tipo de carga.
Las cargas iguales (positivo con positivo, o negativo con negativo) se repelen, mientras que las cargas diferentes (positivo con negativo) se atraen.
Fluorine, chlorine, and bromine react with gold.
which 1 of the 3 elements will be the most reactive with gold
thanks
Answer:
gold i believe or possibly bromine
Explanation:
q- how does fluorine react with gold
a- this fluoride compound features gold in its highest known oxidation state. this red solid dissolves in hydrogen fluoride, but these solutions decompose, liberating fluorine.
q- how does chlorine react with gold
a- gold does react with halogens. it'll, for example, react very slowly with chlorine gas at room temperature to form gold chloride, AuCl3. if gold chloride is heated gently, it will decompose to release the pure elements again.
q- how does bromine react with gold
a- gold in bromine solutions dissolves according to electrochemical/chemical (EC) mechanisms. ... in the chemical composition of the mechanism, this monovalent gold bromide disproportionate into gold and stable AuBr −4 , which reports into solution. with respect to pH, there are two characteristic dissolution regions.

Fluorine will be most reactive with gold.
What is fluorine?
Of almost all of the elements, fluorine seems to be the most electronegative as well as reactive. Fluorine would be a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen would that be. It produces oxygen and even the incredibly corrosive hydrofluoric acid when it combines strongly with water.
What is reactive?Reactivity would be a substance's capacity to chemically combine with several other substances. Iron, for instance, reacts vigorously with oxygen.
As you move down the group, the halogens, which are non-metal elements in Group 7, become less reactive. In contrast to the alkali metals within Group 1 of the particular periodic table, this trend is the opposite. One of the most reactive elements in Group 7 was fluorine.

What is Calcium nitrate?
Calcium nitrate, also called Norgessalpeter (Norwegian salpeter), is an inorganic compound with the formula Ca(NO3)2(H2O)x. The anhydrous compound, which is rarely encountered, absorbs moisture from the air to give the tetrahydrate. Both anhydrous and hydrated forms are colourless salts. Calcium nitrate is mainly used as a component in fertilizers, but it has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence where manure contacts concrete or limestone in a dry environment as in stables or caverns. A variety of related salts are known including calcium ammonium nitrate decahydrate and calcium potassium nitrate decahydrate.

the process shown was used by Mendel during his experiments. What is the process called?
Answer: cross-pollination
Explanation:
Write a balanced chemical equation based on the following description:
aqueous potassium phosphate reacts with aqueous nickel(II) bromide to
produce solid nickel(II) phosphate and aqueous potassium bromide.
the balanced chemical equation was shown here :
2 K3PO4 (aq) + 3 NiBr2(aq) ------------>> Ni3(PO4)2 (s) + 6 KBr (aq)
The balanced chemical equation when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide is:
2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6 KBr(aq)
Let's consider the unbalanced chemical equation that occurs when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide.
K₃PO₄(aq) + NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + KBr(aq)
We will balance it using the trial and error method.
We will balance Ni atoms by multiplying NiBr₂ by 3.We will balance P atoms by multiplying K₃PO₄ by 2.2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + KBr(aq)
We will get the balanced equation by multiplying KBr by 6.
2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6 KBr(aq)
The balanced chemical equation when aqueous potassium phosphate reacts with aqueous nickel(II) bromide to produce solid nickel(II) phosphate and aqueous potassium bromide is:
2 K₃PO₄(aq) + 3 NiBr₂(aq) ⇒ Ni₃(PO₄)₂ + 6 KBr(aq)

How many grams of magnesium
sulfate (MgSO4) are dissolved in
0.965 L of a 0.0575 M solution?
Molar Mass Mg: 24.30 g/mol
Molar Mass S: 32.06 g/mol
Molar Mass O: 16.00 g/mol
Explanation:
Concentration question....
0.965L x (0.0575 mol MgSO4 / 1L) x (120.4g MgSO4 / 1 mol MgSO4) = 6.68g MgSO4
The concept molarity is used here to determine the grams of magnesium sulfate dissolved in 0.965 L of a 0.0575 M solution. The mass of magnesium sulfate in grams is 6.68 g.
What is molarity?The molarity of a solution is defined as the number of moles of the solute present per litre of the solution. It is generally represented by the unit mol/L. The equation used to calculate the molarity is:
Molarity = Number of moles of the solute / Volume of the solution in litres
The molar mass of MgSO₄ = 120.36 g/mol
We have 0.0575 M solution.
That is 0.0575 mol/L × 120.36 g/mol = 6.9207 g/L
Here we want mass in 0.965 L. So the mass is:
Mass = 0.965 L × 6.9207 g/L = 6.68 g
Thus the mass in grams of magnesium sulfate is 6.68 g.

Can carbon and hydrogen form double bonds between them?
Answer:
Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
The carbon-hydrogen bond (C–H bond) is a bond between carbon and hydrogen atoms that can be found in many organic compounds. This bond is a covalent bond meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable.

What is the molarity of .65 L of solution containing 63 grams of NaCl? (dont forget to convert grams to moles)
Answer:
1.66 M
Explanation:
Molarity = moles/L solution
We have the following data:
mass NaCl = m = 63 g
volume of solution = V = 0.65 L
Thus, we first convert the mass to moles with the molar mass of NaCl (MM):
MM(NaCl) = 23 g/mol Na + 35.4 g/mol Cl = 58.4 g/mol
moles NaCl = m/MM = 63 g/(58.4 g/mol)= 1.08 mol
Finally, we divide the moles into the volume of solution to calculate the molarity:
M = moles NaCl/V = 1.66 mol/L
Use the kinetic energy equation to explain why speed has a greater impact on kinetic energy than mass.
Answer: Hopefully this helps! sorry if not. :))
Speed has a greater impact on mass because its increases in velocity have an exponentially greater impact on translational kinetic energy because kinetic energy is proportional to velocity squared. Doubling an object's mass would only double its kinetic energy, however doubling its momentum would quadruple its velocity.
