12 moles H

2

O

Explanation:

Your tools of choice for stoichiometry problems will always be the mole ratios that exist between the chemical species that take part in the reaction.

As you know, the stoichiometric coefficients attributed to each compound in the balanced chemical equation can be thought of as moles of reactants needed or moles of products formed in the reaction.

In your case, the balanced chemical equation for this synthesis reaction looks like this

2

H

2(g]

+

O

2(g]

→

2

H

2

O

(l]]

Notice that the reaction requires  

2

moles of hydrogen gas and  

1

mole of oxygen gas to produce  

2

moles of water.

This tells you that the reaction produces twice as many moles of water as you have moles of oxygen gas that take part in the reaction.

You know that your reaction uses  

6.0

moles of oxygen. Assuming that hydrogen gas is not a limiting reagent, you can say that the reaction will produce

6.0

moles O

If a wave has a wave height of 5 meters, in what depth of water would it begin to break?
Marysya12 [62]

Answer:

6.5 meters

Explanation:

Background Knowledge:

The most familiar example of breaking wave is the breaking of water surface waves on a coastline.

Explanation:

The process of Wave breaking in most of the cases occurs when the amplitude reaches the point that the crest of the wave actually overturns

Factors by which waves are produced:

Different type of waves are produced and varied according to different type of factors. These factors are

Wind direction

Type of swell

Sea floor features

Slope of sea bed

Direct answer of the question:

In general rule, Waves start to break on reaching a water depth of 1.3 times the wave height.

In this question wave height is 5 meters so wave breaks on

5 × 1.3 = 6.5 meters

If winds blow against a mountain from the south, then on which slope would you find the least precipitation?
Aleksandr-060686 [28]

The northern slope will have the least precipitation if winds blow against a mountain from the south.

<h3>What is Slope?</h3>

This is referred to as the degree of steepness on a surface such as rocky areas etc.

When wind blows on the southern part of a mountains, it gets stuck which is why the northern slope have the least precipitation.

1. If 80.0 ml of 3.00 M HCl is used to make a 100. ml of dilute acid, what is the molarity
Aleonysh [2.5K]

<u>We are given:</u>

M1 = 3 Molar        V1 = 80 mL

M2 = x Molar        V2 = 100 mL

<u>Finding the molarity:</u>

We know that:

M₁V₁ = M₂V₂

where V can be in any units

(3)(80) = (x)(100)

x = 240/100                                          [dividing both sides by 100]

x = 2.4 Molar
