Answer:95.211 grams  are in mgcl2

Explanation: Since one mole of MgCl2 consists of one mole of magnesium and two moles of chlorine, the mass of one mole of MgCl2 must be the sum of the masses of the elements. To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23.

Why is the sky orange and red at sunrise and sunset?
Allushta [10]

Answer:

gas molecules scatter short wavelengths of light (blue and violet) more than long (red and orange) so the sky looks blue. at sunrise and sunset, the light passes through thicker atmosphere and blue light is scattered more, so mostly red and orange light is visible.

The immediate source of energy that powers a cell’s activities is
Alja [10]
<span>1. The correct option is ADENOSINE TRIPHOSPHATE, ATP. ATP is the basic unit of energy transfer in the living cells. ATP is the principal energy source for metabolic functions, in the cells, ATP are consumed by endothermic metabolic reactions and they are produced by exothermic metabolic reactions.

2. To form ATP, A THIRD PHOSPHATE GROUP HAS TO BE ADDED TO ADP. ADP has two phosphate groups while ATP has three phosphate group. ADP is usulally converted to ATP by the addition of a single phosphate group.

3. ADP and ATP work together and the two can be interconverted. ATP can be hydrolysed to ADP and ADP can be converted to ATP by the addition of a single phosphate group. When energy is needed inside a cell, the ATP will split off one of its phosphate group and become ADP. This split off process produce a high qunatity of energy which is then available for the cell to use.</span>

What is the coordination number for each of the following complexes or compounds? [Co(NH3)4(H2O)2]3+ [Cr(EDTA)]− [Pt(NH3)4]2+ Na
Burka [1]

Answer:

[Co(NH₃)₄(H₂O)₂]³⁺: coordination number = 6.

[Cr(EDTA)]⁻: coordination number = 6.

[Pt(NH₃)₄]²⁺: coordination number = 4.

Na[Au(Cl)₂]: coordination number = 2.

Explanation:

  • [Co(NH₃)₄(H₂O)₂]³⁺:

In this complex, Co is bonded with 4 molecules of NH₃ (with 4 coordinate bonds, one bond for each molecule) and 2 molecules of H₂O (with 2 coordinate bonds, one bond for each molecule) forming the complex with 6 coordinate bonds.

∴ coordination number = 6.

  • [Cr(EDTA)]⁻:

In this complex, Cr is bonded with 1 molecules of EDTA (with 6 coordinate bonds, 4 O atoms and 2 N atoms in EDTA molecule).

∴ coordination number = 6.

  • [Pt(NH₃)₄]²⁺:

In this complex, Pt is bonded with 4 molecules of NH₃ (with 4 coordinate bonds, one bond for each molecule).

coordination number = 4.

  • Na[Au(Cl)₂]:

In this complex, Au is bonded with 2 atoms of Cl (with 2 coordinate bonds, one bond for each atom).

coordination number = 2.
