Answer:
The answer is 130.953 g of hydrogen gas.
Explanation:
Hydrogen gas is formed by two atoms of hydrogen (H), so its molecular formula is H₂. We can calculate is molecular weight as the product of the molar mass of H (1.008 g/mol):
Molecular weight H₂= molar mass of H x 2= 1.008 g/mol x 2= 2.01568 g
Finally, we obtain the number of mol of H₂ there is in the produced gas mass (264 g) by using the molecular weight as follows:
mass= 264 g x 1 mol H₂/2.01568 g= 130.9731703 g
The final mass rounded to 3 significant digits is 130.973 g
Answer:
The answer is...
Explanation:
Smaller crystals have more surface area.
Answer:
2+
Explanation:
The charge on Z in the compound ZB₂ is a 2+
From the given compound:
We know that Br is bromine with a charge of -1;
So;
Using the combining power approach:
Atoms Z Br
Combining power 2 1
Exchange of valency 1 2
So;
The charge on Z is 2+
2
Answer:
An autotroph absorbs sunlight from their stoma and converts this solar energy to chemical energy with their chloroplasts. As you can see, the sun's interaction of matter and energy is vital to sustaining all living things on Earth.
