How does a balanced chemical equation show that mass is conserved

Chemistry
1 answer:
Ronch [10]3 years ago
8 0
Atoms make up the mass of all materials

Atoms cannot be created or destroyed

So in a balanced chemical equation, all atoms are accounted for, and therefore all mass is accounted for and conserved.

How does parallax affect vision with each eye
kaheart [24]

Answer:

Depth Preception

Explanation:

Each eye sees a diffrent angle of a object. This is because the horizontal separation parallax of the eyes. If the object is close or near by the disparity will be huge.

Which of the following statements is not true of the process of nuclear fission? (3 points) It is the process used in most nucle
Misha Larkins [42]
Answer: the statement that is not true is the second one: <span>It only occurs in very small atoms with low mass.

Explanation:

</span><span>The nuclear fission consists in the division or fragmentation of an atomic nuclei into smaller fragments releasing huge amounts of energy.

The biggest and heaviest atoms are unstable, meaning that they gain stability by splitting into smaller, lighter atoms.

So, the third given statement contradicts the previous fact.

That is why most of the heaviest elements have not been found naturally but have been created synthetically and have very short life times.

How many moles of carbon do you have in a trillion carbon
Dmitry_Shevchenko [17]

Answer:

1.7\times 10^{-12} moles of carbon

Explanation:

1 trillion = 10^{12}

Avogadro number :It is the number of particles that are present in 1 mole of substance.

N_{0} = 6.022\times 10^{23}

So,

6.022\times 10^{23} atoms = 1 mole carbon

1 atom =

\frac{1}{6.022\times 10^{23}} mole

1 trillion atom =

\frac{1}{6.022\times 10^{23}}\times 10^{12} mole

1.660\times 10^{-12} mol

Two significant figure

1.7\times 10^{-12} moles of carbon

Question 15 (5 points)
Vladimir [108]

This problem is providing us with the maximum mass of Imitrex a patient can get daily as 0.2 g. Also, the mass of a tablet is given as 25 mg so the number of tablets they get in a day is required. After the calculations, the result turns out to be 10 tablets.

<h3>Dimensional analysis:</h3>

In chemistry, dimensional analysis is used to calculate specific outcomes given useful information to do so. Despite not having specific formulas for every problem, one can come up with a feasible proportional-factor-based setup, in order to obtain the required.

In this case, since the mass per tablet is 25 mg, one can divide the maximum dosage by this mass per tablet, both in grams, to obtain the required number of tablets for a daily dosage:

25\frac{mg}{tablet}*\frac{1g}{1000mg}=0.025\frac{g}{tablet}  \\\\\#tablets=\frac{0.25g}{0.025\frac{g}{tablet}} \\\\\#tablets=10 tablets
