Answer:

42.3moles

Explanation:

The chemical equation given in this question is as follows:

H2 + O2 → H2O

However, this equation is unbalanced, the balanced chemical equation is as follows:

2H2 + O2 → 2H2O

This equation shows that;

2 moles of hydrogen gas (H2) will produce 2 moles of water (H2O)

Hence, If 42.3 moles of water (H2O) are produced, 42.3 × 2/2

= 42.3moles of hydrogen was reacted.

Answer:

You need to measure 120.9132 grams of MgO and add to 1 liter of distilled water in a beaker.

Explanation:

Capital M stands for molarity, or moles/liter. So 3 M MgO means 3 moles per liter of MgO.

1 L × [tex]\frac{3 moles MgO}{1 L MgO}[/tex] = 3 moles MgO

This means you need to measure 3 moles MgO to put into 1 Liter of water.

But you don't know how much that is, so you need to convert moles to grams.

First you need to find how many grams are in 1 mole of MgO.

You can search the molar mass of MgO online to get: 40.3044 g

But if you don't have the internet, use the periodic table to add the masses of Mg and O: 24.305 g + 15.999 g = 40.3044 g

Then write the fraction so that the units cancel out, so you get grams by itself on the top of the fraction.

1 L × [tex]\frac{3 moles MgO}{1 L MgO}[/tex] × [tex]\frac{40.3044 g MgO}{1 mole MgO}[/tex] = 120.9132 g MgO

You need to measure 120.9132 grams of MgO and add to 1 liter of distilled water.

We will prepare 1 L solution of 3 M MgO, by dissolving 120.91 grams of MgO in 1 litre of water.

Molarity is define as the no. of moles of solute dissolve in per liter if solvent or solution & it is represented as:

M = n / v

In the question, it is given that:

Molarity of MgO = 3M i.e. 3 moles of MgO is present in 1 liter of solution.

So, we have moles of MgO = 3 moles

Now, we convert moles of MgO to grams to know how much of solute is required, in the following manner:

n = W / M, where

M = molar mass of MgO = 40.30 g/mole

W = to find?

W = 3 mole × 40.30 g/mole = 120.91 grams

Hence, 120.91 grams of MgO is required.

Answer: This is the magic element for everything on Earth. All life on Earth depends on carbon (C). It is in nearly every biological compound that makes up our bodies, systems, organs, cells, and organelles. When you breathe out, there is a lot of carbon dioxide (CO2).

Explanation:

Answer:

Like Carbon dioxide? or just like carbon? well anyway we breath in oxygen and breath out carbon the carbon goes into the air and gets re-cleaned turned into oxygen again. And also thousands of cars that run everyday going places let out tons of carbon into the the air every minute. (aka which is bad for human society, considering there's probably more carbon in the air then there is oxygen.)

So yes carbon does apply in everyday life. By the way the other person is right too. :)

Explanation:

When we rediscover something that we had missed years ago we feel very happy. This happiness will come in everyone's face without any difference in the ages.

The term rediscover indicates to find something or someone again after losing or forgetting about it, him, or her for a long time. For example in child hood days we all have gone to parks. But now all those parks are a happy rediscovery of childhood.

When i was in the age of 5 my grandfather gifted me a beautiful necklace of gold. I used to wear that in all functions. But one day when i searched it was not at my room. I cried a lot during that time.

But after 5 years, when we are shifting to a new home all the places of our old home is cleaned. During cleaning i got my necklace from an old utensil in the store room. This time i just shocked, i didn't thought that it will again come into my hand.

Answer: Chromium is less reactive as compared to Aluminium as it can not easily electrons as aluminium.

Explanation:

The arrangement of metals in a series according to the decreasing order of their reactivity is called reactivity series.

The metals that are placed above hydrogen are more reactive and those below hydrogen are less reactive.

A metal placed above another metal can displace lower metal from its salt solution. Thus a metal placed above in series is more reactive than metals placed below it.

As aluminium can easily lose electrons as compared to chromium , it is more reactive than Chromium.
