G the hydrogen generated in this lab was a product of the reaction between magnesium and hydrochloric acid. which of these react
Colt1911 [192]

The limiting reactant is determined by the supply and stoichiometric equation.

<h3>Limiting reactants</h3>

They are reactants that are limited in availability, and thus, determine how far reactions can go in terms of producing products.

In a reaction involving magnesium and hydrochloric acid to produce hydrogen gas as follows:

Mg + 2HCl --- > MgCl_2 + H_2

The number of moles of HCl is twice that of Mg. Thus, if both reactants are supplied in the required proportion, no reactant will be limiting.

However, if the number of moles of HCl supplied is not up to twice that of Mg, HCl will become limiting. Also, if the amount of Mg supplied is not equal to half of that of HCl supplied, Mg will be limiting.

How many hours are there in 34.5 years
4vir4ik [10]

Hi,

Answer: 30,2220 Hours

<u>My work:</u> There are 60 minutes in every hour and 8,760 hours in a year. To,easily achieve this problem you take 8,760 the hours in a year and multiply it with 34.5. (8,760 * 34.5) By doing this you get your answer of 302,220 Hours, or in minutes it would be 18,133,200 minutes.

If the heat of fusion for water is 334 j/g, how many Jules are needed to melt 45.0 g of ice at 0.0°c?
finlep [7]

Given parameters:

Heat of fusion of water  = 334j/g

Mass of ice  = 45g

Temperature of ice =  0.0°c

Unknown:

Amount of heat needed to melt = ?

Solution:

This is simply a phase change and a latent heat is required in this process.

  To solve this problem; use the mathematical expression below;

             H  = mL

where m is the mass

            L is the heat of fusion of water;

              H  = 45 x 334  = 15030J
