Looking at choices, Mg has a positive charge in the compound so it is a metal and Cl2 is a non-metal (negative charge), so it is sonic since they contain a metal and non metal, where metal transfers electrons to non-metal thus having a positive charge, and non-metal has negative

Answer: MgCl2

MgCl2 because it is the only option in which a metal appears with a nonmetal. In this case, the metal transfers electrons to the nonmental because the metal has a lower ionization energy.

How many types of atoms in this picture?
weqwewe [10]

Answer:

Nitrogen (N), carbon (C), hydrogen (H) and oxygen (O).

Explanation:

Hello,

Given the shown organic compound, we refer to types of atoms to the elements present in the compound, thus, we find nitrogen (N), carbon (C), hydrogen (H) and oxygen (O) that are bonded via single or double bonds in such compound.

Let's remember that compounds like that, having those elements are mainly found in biochemical substances such as proteins, a very important source of benefits for our body.

Regards.

A solution is prepared from 4.5701 g of magnesium chloride and 43.238 g of water. The vapor pressure of water above this solutio
balandron [24]

Answer:

i = 2.483

Explanation:

The vapour pressure lowering formula is:

Pₐ = Xₐ×P⁰ₐ <em>(1)</em>

For electrolytes:

Pₐ = nH₂O / (nH₂O + inMgCl₂)×P⁰ₐ

Where:

Pₐ is vapor pressure of solution (<em>0.3624atm</em>), nH₂O are moles of water, nMgCl₂ are moles of MgCl₂, i is Van't Hoff Factor, Xₐ is mole fraction of solvent and P⁰ₐ is pressure of pure solvent (<em>0.3804atm</em>)

4.5701g of MgCl₂ are:

4.5701g ₓ (1mol / 95.211g) = 0.048000 moles

43.238g of water are:

43.238g ₓ (1mol / 18.015g) = 2.400 moles

Replacing in (1):

0.3624atm = 2,4mol / (2.4mol + i*0.048mol)×0.3804atm

0.3624atm / 0.3804atm = 2,4mol / (2.4mol + i*0.048mol)

2.4mol + i*0.048mol = 2.4mol / 0.9527

2.4mol + i*0.048mol = 2.5192mol

i*0.048mol = 2.5192mol - 2.4mol

i = 0.1192mol / 0.048mol

<em>i = 2.483</em>

<em />

I hope it helps!

Time (sec) [CH4] (mol/L)
Oxana [17]

Based on the table and the equation of reaction; the

  • rate of consumption of oxygen between time 20 and 40s is 0.005 M/s
  • rate of consumption of oxygen between time 40 and 60s is 0.0025 M/s

<h3>What is rate of a reaction?</h3>

The rate of a reaction is the rate at which reactants molecules are consumed or products are formed.

  • Rate of reaction = change in concentration of reactants or products/ time taken

Based on the equation of reaction, the rate of consumption of oxygen is equal to the rate of consumption of methane.

Thus. rate of consumption of oxygen from time 20 seconds to time 60 seconds is calculated as follows:

Rate between 20 and 40 = 1.0 - 0.9/20

  • Rate of consumption of oxygen = 0.005 M/s

Rate between 40 and 60 = 0.9 - 0.85/20

  • Rate of consumption of oxygen = 0.0025 M/s

Therefore, the rate of consumption of oxygen decreases with time.
