Answer:-
The hydrogen atoms have partial positive charges
Explanation:-
In a water molecule there are twp atoms hydrogen and oxygen.
Oxygen has more electronegativity than hydrogen. So the electrons in the bond between Oxygen and hydrogen are more towards oxygen. So hydrogen has a partial positive charge.
The Cl- has negative charge. Positive charge is attracted by negative charge.
Due to this hydrogen atoms in a water molecule are attracted to Cl- ions in sodium chloride (NaCl).
they are outside the body, because they need to be cooler than the temperature inside the body so sperm can be made. hope this helped you <3
The mass in grams of each of the following using dimensional analysis is:
- 6.02 x 10²³ atoms of Mg = 12g of Mg
- 3.01 x 10²³ formula units of CaCl2 = 55.5g of CaCl2
- 12.4 x 10¹⁵ molecules of formaldehyde (CH2O) = 0.000000618g of formaldehyde
<h3>How to calculate mass?</h3>
The mass of a substance can be calculated in different ways depending on whether molecules or moles are given.
First, we need to convert atoms/formula units/molecules to moles as follows:
- 6.02 × 10²³ ÷ 6.02 × 10²³ = 1 mole of Mg
- 3.01 x 10²³ ÷ 6.02 × 10²³ = 0.5 moles of CaCl2
- 12.4 x 10¹⁵ ÷ 6.02 × 10²³ = 2.06 × 10-⁸ moles of formaldehyde
Next, we convert each mole value to mass as follows:
- 1 mole of Mg = 1 × 12 = 12g of Mg
- 0.5 moles of CaCl2 = 0.5 × 111 = 55.5g of CaCl2
- 2.06 × 10-⁸ moles of CH2O = 0.000000618g of formaldehyde

Answer:
Lustrous is NOT a property of metal
<span>At much higher temperatures, nitrogen reacts with oxygen to form nitric oxide, but this takes a considerable spark of energy. In the upper atmosphere during a lightning storm, nitrogen and oxygen react and the resulting nitric oxide further reacts with water to form nitric acid. When it rains, this nitric acid is carried down to Earth and forms compounds with other elements. Nitrates and nitrites are a few of the results.</span>
