Answer:
[MgSO₄] = 890 mM/L
Explanation:
In order to determine molarity we need to determine the moles of solute that are in 1L of solution.
Solute: MgSO₄ (10.7 g)
Solvent: water
Solution: 100 mL as volume. (100 mL . 1L / 1000mL) = 0.1L
We convert the solute's mass to moles → 10.7 g / 120.36 g/mol = 0.089 moles
Molarity (mol/L) → 0.089 mol/0.1L = 0.89 M
In order to calculate M to mM/L, we make this conversion:
0.89 mol . 1000 mmoles/ 1 mol = 890 mmoles
Answer:
compound
Explanation:
When two distinct elements are chemically combined—i.e., chemical bonds form between their atoms—the result is called a chemical compound. Most elements on Earth bond with other elements to form chemical compounds, such as sodium (Na) and Chloride (Cl), which combine to form table salt (NaCl).
The answer is 0.492 because there are 100 meters in a hectometer, and 49.2/100 is 0.492
Answer:
FALSE
Explanation:
Ionic bonds are when two atoms of OPPOSITE CHARGE bond together by sharing electrons. For example Na and Cl have opposite charges and they form ionic bonds. Thus two negatively charged particles aren't oppositely charged so they can't be ionic bonds so the statement is FALSE.
The answer would be: carbon dioxide(CO2) and water (H2O).
The combustion of methane gas family typically will result in carbon dioxide and water. It will need many oxygen gases to do the combustion. The reaction equation would be:
