Answer:

"Like when people say like im a party fowl but I'm like OMg, I'm like the reason everyone loves the 4th of July like I am 4th of July.

Explanation:

As magnesium ignites easily in air and burns with a bright light, it's used in flares, fireworks and sparklers. I imagine Magnesium talks like a valley girl lol.

what are the mole ratios of hydrazine (n2h4) to hydrogen peroxide (h2o2) and hydrazine to water? 1:2 and 1:4 1:3 and 1:4 1:2 and
Shalnov [3]
To determine the mole ratios of the substances, we need to know the balanced chemical reaction of the system. The reaction between hydrazine and hydrogen peroxide yields to nitrogen and water. The balanced chemical reaction is:

N2H4 + 2H2O2 --> N2 + 4H2O

Therefore, the mole ratio between hydrazine and hydrogen peroxide is 1:2 and the mole ratio between hydrazine and water is 1:4.

Electron affinity is the measure of the attraction of an electron toward an isolated gaseous atom. When an electron is added to
zhuklara [117]

False

Explanation:

Electron affinity is negative when energy is absorbed and it is positive when energy is released.

Electron affinity is defined as the energy released in adding an electron to a neutral atom in the gas phase.

It is a measure of the readiness of an atom to gain an electron.

In a reaction where energy is released, electron affinity is usually positive. These reactions are called exothermic reactions.

Endothermic reactions in which energy is absorbed have negative electron affinity values.

How many grams of hydrogen chloride can be produced from 1.00g of hydrogen and 55.0g of chlorine? what is the limiting reactant?
zloy xaker [14]

Answer:

m_{HCl}=36.1gHCl

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to calculate the required grams of HCl by firstly identifying the limiting reactant via the moles of each reactant as they are in a 1:1 mole ratio:

n_{H_2}=1.00gH_2*\frac{1molH_2}{2.02gH_2}=0.500molH_2\\\\ n_{Cl_2}=55.0gCl_2*\frac{1molCl_2}{70.9gCl_2}=0.776molCl_2

Thus, we infer the hydrogen is the limiting reactant and therefore we use its 1:2 mole ratio with HCl whose molar mass is 36.46 g/mol:

m_{HCl}=0.500molH_2*\frac{2molHCl}{1molH_2}*\frac{36.46gHCl}{1molHCl}\\\\m_{HCl}=36.1gHCl

Regards!
