A student tested a 0.1 M aqueous solution and made the
following observations conducts electricity, turns blue litmus to red and reacts
with Zn(s) to produce gas bubbles. The compound that could be the solute in
this solution is HBr. The answer is number 3.
Answer:
on the right side of the equation and are called products
Explanation:
Reactants are on the left side of the equation. When reactants react, they give products.
Products formed are at the right side of the equation.
They are directed as reactant to product using an arrow pointing towards the products.
New substances formed are called products. Several By-Products can also be formed . They are also on the right hand side.
Answer:
55.18 L
Explanation:
First we convert 113.4 g of NO₂ into moles, using its molar mass:
- 113.4 g ÷ 46 g/mol = 2.465 mol
Then we<u> use the PV=nRT formula</u>, where:
- P = 1atm & T = 273K (This means STP)
- R = 0.082 atm·L·mol⁻¹·K⁻¹
Input the data:
- 1 atm * V = 2.465 mol * 0.082atm·L·mol⁻¹·K⁻¹ * 273 K
And <u>solve for V</u>:
Answer:
The biochemical properties of water are 1) chemical structure of water 2) water is a good solvent 3) hydrogen bonding. 4) sticky, wet water 5)the density of ice and water
