Answer:</h3>
The conservation of mass and matter is true
<h3>
Explanation:</h3>
- The law of conservation of mass requires that the mass of reactants and products be equal in chemical reactions.
Given the equation;
AgNO₃ + HCI → AgCI + HNO₃
- The equation is balanced because, it has 1 silver atom, 1 nitrogen, 3 oxygen atoms, 1 hydrogen atom, and 1 chloride atom on both side of the equation.
- Therefore, the mass of the reactants and the products is equal which makes the law of conservation of mass hold.
- The conservation of matter is also true since the reaction process without changing the number of atoms of each element.
Answer:
0.585 mol
25.7 g
Explanation:
There is some info missing. I think this is the complete question.
<em>Carbon dioxide gas is collected at 27.0 °C in an evacuated flask with a measured volume of 30.0L. When all the gas has been collected, the pressure in the flask is measured to be 0.480atm.
</em>
<em>
Calculate the mass and number of moles of carbon dioxide gas that were collected. Be sure your answer has the correct number of significant digits.</em>
<em />
Step 1: Given data
T = 27.0°C + 273.15 = 300.2 K
V = 30.0 L
P = 0.480 atm
n = ?
m = ?
Step 2: Calculate moles of CO₂
We can calculate the moles of CO₂ using the ideal gas equation.
Step 3: Calculate mass of CO₂
We know that the molar mass is 44.01 g/mol. Then,
The answer is E and F.
Hope this helps!!
Ionic bonds is formed between a metal and a nonmetal because the metal transfers it's valence electrons to the nonmetal. Electrons doesn't transfer between two nonmetal because both are negatively charged.
