It is in period 3
It is in group 17
It is a chlorine atom because it has 17 electrons which means the atomic number is 17
Answers are:
Catabolism:
- g<span>enerally exergonic (spontaneous): In this reactions energy is released.
- </span><span>convert NAD+ to NADH. Electrons and protons released in reactions are attached to NAD+.
- </span><span>generation of ATP. ATP is synthesis from ADP.
- </span><span>convert large compounds to smaller compounds. Foe example starch to monosaccaharides.
Anabolism:
</span><span>- convert NADPH to NADP+. Protons and electrons are used to make chemical bonds.
</span>- <span>convert small compounds to larger compounds.</span>
Answer:
0.01504 mol/dm3
Explanation:
Calcium Hydroxide - Ca(OH)2
Hydrochloric acid - HCl
The reaction between both is given as;
2HCl + Ca(OH)2 --> CaCl2 + 2H2O
2 : 1
The relationship between the concentration and volume is given as;
CaVa / CbVb = na / nb
where a = acid (HCl) and b = base Ca(OH)2
Inserting the values;
0.04 * 18.8 / (Cb * 25) = 2 / 1
0.752 / 25Cb = 2
Cb = 0.752 / 50 = 0.01504
It is important to note that mass and mole pertain to different units of measurement, thus, 1 mole of one substance may have a lower or higher mass compared to a different substance. The mass of an object gives a measure of the number of atoms present in the substance while the number of moles of a substance refers to the amount of a chemical substance it has and is often used for chemical reactions.
For this problem, we first get the molar mass of each substance:
Molar mass of H2O = 18.0153 g/mol
Molar mass of C6H12O6 = 180.1559 g/mol
We then convert each substance into units of mass (grams), where:
1 mol H20 x 18.0153 g/mol = 18.0153 g H20
1 mol C6H12O6 x 180.1559 g/mol = 180.1559 g C6H12O6
It was then determined that 1 mole of glucose has more mass than 1 mole of water.
