Answer:

Following are the responses to the given question:

Explanation:

They told everyone to "think of the source of energy which perfectly responds to needs of society." It's why I would like to point out though those dynamos could be used to generate electricity using rotating cycles which can be used in gyms. The above conduits are indeed very regular used in this gym and could be the cheapest, ecologically responsible, highly reliable because it contributes to international access, is really very stable and can probably not cause damage, as well as the provision, can also be very large if we can create it.

3Co2 (aq) 6NO3(aq) 6Na (aq) 2PO43–(aq) → Co3(PO4)2(s) 6Na (aq) 6NO3(aq) Identify the net ionic equation for this reaction.

Burka [1]

Answer : The net ionic equation will be,

$3Co^{2+}(aq)+2PO_4^{3-}(aq)\rightarrow Co_3(PO_4)_2(s)$

Explanation :

In the net ionic equations, we are not include the spectator ions in the equations.

Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.

The given balanced ionic equation will be,

$3Co^{2+}(aq)+6NO_3^-(aq)+6Na^+(aq)+2PO_4^{3-}(aq)\rightarrow Co_3(PO_4)_2(s)+6Na^+(aq)+6NO_3^-(aq)$

In this equation, $NO_3^-(aq)\text{ and }Na^+(aq)$ are the spectator ions.

By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.

Thus, the net ionic equation will be,

$3Co^{2+}(aq)+2PO_4^{3-}(aq)\rightarrow Co_3(PO_4)_2(s)$

Caroline has a condition where the amount of oxygen her blood can hold is greatly reduced. This leads to a decrease in oxygen su

Sphinxa [80]

The correct answer is : Circulatory and respiratory.

This condition primarily affects Caroline's circulatory system. Since the main purpose of the circulatory system is to supply the rest of the body with oxygen, this condition is greatly reducing the effectiveness of the circulatory system.
The decrease in oxygen supply to the lungs causes the reduction of the respiratory system effectivness as well, since the lung cells need oxygen for their metabolic processes.

Calculate molecules in 1dm^3 of oxygen

Archy [21]

Number of molecules in 1 dm³ Oxygen = 2.71 x 10²²

<h3>Further explanation</h3>

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

1 dm³ of oxygen = 1 L Oxygen
