1. How does the period (row) in which an element is located relate to the number of shells that contain electrons?

Chemistry

Kamila [148]3 years ago
4 0

1. The period number tells us about the number of shells in an element(for example Na located in third period has three electron shells)

2. Group number tells us the amount of electrons present in the valence shell thus also tells us about the ionic charges they form

3. They all have a stable electronic configuration with complete valence shells hence they also don't form ions.

Rasek [7]
<h3>Answer:</h3>

2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat

<h3>Explanation:</h3>
  • Balancing chemical equations involves putting coefficients on reactants and products.
  • This results in an equal number of atoms of each element on either side of the equation.
  • Balancing chemical equations ensures that the law of conservation of mass is obeyed.
  • According to the law of conservation of mass, the mass of the reactants should be equal to the mass of products which is done by balancing chemical equations.
  • Putting the coefficients, 2, 3, 4, 4, 4 on the equation makes the equation balanced.
  • Therefore, the balanced equation would be;

       2(CH3)2N2H2 + 3N2O4 → 4N2 + 4H2O + 4CO2 + heat

What fuel source is Jan using if she exercises at 85% of her maximum aerobic capacity?
Marina86 [1]

Answer:

Carbohydrates

Explanation:

Increased exercise intensity means the overall need for energy increases. As we increase exercise intensity we increase our glucose uptake and oxidation which far exceeds uptake, indicating that muscle stores of glycogen are being used. At moderate intensities (65%) there is an increased need for muscle glycogen and muscle triglycerides which is fat. At higher levels of intensities (85%) there is an even greater need for energy, and this is met almost solely by an increased uptake of glucose from the blood and from muscle glycogen.

In the case of fats as an energy fuel source at high intensities, increasing levels of intensity increases fat oxidation but once we get into higher levels of intensity, we return to levels of fat oxidation similar to very low intensities.
