Answer:

0 kgm/s

Explanation:

The momentum of Bob while resting at the river is 0 kgm/s.

This is because the momentum of any object at rest is 0.

 Momentum is the quantity of motion a body contains. It is mathematically expressed as;

  Momentum  = m x v

m is the mass

v is the velocity

 So at rest, the velocity of a body is 0m/s and therefore, the momentum is O

<u>Answer:</u>

Glow sticks give off light but not heat because energy is released, the glow stick reaction is an example of exergonic (energy-releasing) reaction. However, it is not an exothermic (heat-releasing) reaction because heat isn't released... endothermic reactions absorb heat.

3. Calculate the mass of NH3 that can be produced from the reaction of 125 g of NCI:
otez555 [7]

The mass of NH₃ : = 17.629 g

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Given

125 g NCl₃

Required

The mass of NH₃

Solution

mol NCl₃(molar mass : : 120.5 g/mol)

= 125 g : 120.5 g/mol

= 1.037

From the equation, mol ratio NCl₃ : NH₃ = 1 : 1, so mol NH₃ = 1.037

Mass NH₃(molar mass : 17 g/mol) :

= 1.037 x 17

= 17.629 g

How many atoms are there in 38 g of iron(Fe) please help
garik1379 [7]

Answer:

Explanation:

1 mole of iron is 56 grams (rounded)

x mole of iron is 38 grams (given

1/x = 56/38                Cross multiply

56x = 38*1                Divide by 56

x = 38/56

x = 0.679 mols of iron

1 mol of anything = 6.02 * 10^23

0.678 mols of iron = x

1/0.679 = 6.02 *10^23 /x

x = 0.679 * 6.02*10^23

x = 4.09 * 10 ^23

So there are 4.09 * 10^23 atoms of Fe in 38 grams of iron

Which soil particle is the smallest, drains water slowly, and holds too much water?
dsp73

Answer:

Clay

Explanation:

Since Clay has a very small particle size it compacts or has a high surface area which slows the path of water, holding it for longer periods compared to other soil components.
