Answer: last option, 0.22 N


Explanation:


<em>Weight</em> is the attractive force that the Earth exerts on the objects, and it is calculated as the product of the mass of the object and the gravitational acceleration: w = mg.


Gravitational acceleration depends of the height of the objects but it is almost a constant at the normal altitudes (near the surface) with which this kind of problems deal with. Of course, this is true at <em>sea level on Earth.</em>


A standard value used for g is 9.81 m/s^2. And for quick or approximate calculations it can be used 10 m/s^2.


So, to calculate what is the<em> weight of a mouse at sea level on Earth</em>, when you have that the mass of a mouse is around 22 grams (0.022kg), you  folow these steps:


1) Data:

  • m = 0.022 kg
  • g = 10 m/s^2
  • w = ?

2) Formula: w = mg


3) Solution: w = 0.022 kg (10 m/s^2) = 0.22 N.


So, the answer is the last option: 0.22N.

What may be expected when K &gt; 1.0?
lora16 [44]

The two correct statements are:

1. The concentration of one or more of the products is small

2. The reaction will proceed to the right and favor the formation of products.

LeChatelier's Principle states that when a stress is imposed on a system at equilibrium, the equilibrium will shift to counteract the change. A reduction in the number of products cause the system to respond by making more product, which leads to K>1 and products being more favorable.

Suppose 1.87g of nickel(II) bromide is dissolved in 200.mL of a 52.0mM aqueous solution of potassium carbonate.
Reika [66]

Answer:

0.0428 M

Explanation:

Because we're asked to calculate the molarity of nickel(II) cation, we need to <u>determine all sources for that species</u>, in this case, all Ni⁺² comes from the nickel(II) bromide solid (NiBr₂).

We use the molecular weight of NiBr₂ to calculate the moles of Ni:

1.87 g NiBr₂ ÷ 218.49g/mol * (1molNi⁺²/1molNiBr₂) =  8.55x10⁻³ mol Ni⁺²

Then we <u>divide the moles by the volume in order to calculate the concentration</u>:

8.55x10⁻³ mol Ni⁺² / 0.200 L = 0.0428 M

Determine the number of moles of H in each sample
MissTica

C. The number of moles of H in 0.109 mole of N₂H₄ is 0.436 mole

D. The number of moles of H in 34 moles of C₁₀H₂₂ is 748 moles

<h3>C. How to determine the number of mole of H in 0.109 mole of N₂H₄</h3>

1 mole of N₂H₄ contains 4 moles of H

Therefore,

0.109 mole of N₂H₄ will contain = 0.109 × 4 = 0.436 mole of H

<h3>D. How to determine the number of mole of H in 34 mole of C₁₀H₂₂</h3>

1 mole of C₁₀H₂₂ contains 22 moles of H

Therefore,

34 mole of C₁₀H₂₂ will contain = 34 × 22 = 748 mole of H
