Answer:
mole
Explanation:
is a unit of amount of substance in the International System of Units, defined (since 2019) by fixing the Avogadro constant at the given value. Sometimes, the amount of substance is referred to as the chemical amount

if it forms from positive ions and has types of metallic bonds
Explanation:
Answer:
0.1159 M
Explanation:
Using the formula below:
CaVa = CbVb
Where;
Ca = concentration/molarity of acid (M)
Cb = concentration/molarity of base (M)
Va = Volume of acid (mL)
Vb = volume of base (mL)
According to this question, the following information were given:
Ca = ?
Cb = 0.2831 M
Va = 26.86 mL
Vb = 11.00 mL
Using CaVa = CbVb
Ca × 26.86 = 0.2831 × 11
26.86Ca = 3.1141
Ca = 3.1141 ÷ 26.86
Ca = 0.1159
The molarity of the acid (H2SO4) solution is 0.1159 M
No
Explanation:
A small rock falling from a cliff is an example of physical weathering. The process breaks the rock mass into small chips of rocks.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- In physical or mechanical weathering, lumps of rocks are broken down into small sizes.
Some of the process involves:
- Pressure release on a rock
- Freezing and thawing
In chemical weathering, a rock undergoes chemical reactions and it becomes weak in the process.
Some of the process involves:
- oxidation
- hydrolysis
- carbonation
