Answer:
2Ga2O3 = 4Ga + 3O2
Explanation:
You need to balance out the equation by making sure there are the same number of elements on each side.
Ga - 4 on each side
O - 6 on each side
Answer:
is a chemical bond i think is true
Answer:
Explanation:
<u>1. Word equation:</u>
- <em>mercury(II) oxide → mercury + oxygen </em>
<u>2. Balanced molecular equation:</u>
<u>3. Mole ratio</u>
Write the ratio of the coefficients of the substances that are object of the problem:
<u>4. Calculate the number of moles of O₂(g)</u>
Use the equation for ideal gases:
<u>5. Calculate the number of moles of HgO</u>
<u>6. Convert to mass</u>
- mass = # moles × molar mass
- molar mass of HgO: 216.591g/mol
- mass = 0.315mol × 216.591g/mol = 68.3g
Answer:
They decrease did the problem
Explanation:
did already if it helps can i have brain pls?
Density =mass /volume
Volume =1800÷0.79
= 2278.481ml
