Is it true that an atom has 3 subatomic particles with a negative nucleus and the neutrons outside the the nucleus

1 answer:

5 0

Answer: atoms do have 3 subatomic particles but the nucleus is positive and the nucleus consists of protons and neutrons. Its positive because neutrons have no charge and protons have a positive charge. There are only electrons on the shells so no neutrons or protons on the shells

Finger [1]

Answer:

Percent yield = 75%

Explanation:

Given data:

Actual yield of ammonia = 60 g

Theoretical yield of ammonia = 80 g

Percent yield = ?

Solution:

Percent yield is calculated dividing the actual yield by theoretical yield and multiply by 100.

Formula:

Percent yield = Actual yield / Theoretical yield × 100

Now we will put the values in formula.

Percent yield = 60 g/ 80 g × 100

Percent yield = 0.75 × 100

Percent yield = 75%

So if the reaction yield is 60 g and calculated yield ( theoretical yield) is 80 g then the percent yield would be 75%.

4. Consider the following statement made in Chapter 4 of the text: "... consider that if the

AveGali [126]

The claim: "If the nucleus were the size of a grape, the electrons would be one mile away on average" is reasonably accurate because the ratios between the nucleus's sizes and the distances (between electrons and nucleus) for the two given examples are in the same order of magnitude.

To know if the claim is accurate we need to calculate the ratio of the size of the nucleus (the same as a grape) and the distance between the electrons and the nucleus for example 1 (r₁):

$r_{1} = \frac{s_{1}}{d_{1}}$ (1)

and to compare it with the ratio of the size and the distance given in example 2 (r₂):

$r_{2} = \frac{s_{2}}{d_{2}}$ (2)

Where:

s₁: is the size of the nucleus (like the size of a grape)

d₁: is the distance between electrons and nucleus of example 1 = 1 mile

s₂: is the average diameter of the nucleus = 10⁻¹³ cm

d₂: is the average distance between electrons and nucleus of example 2 = 10⁻⁸ cm

Assuming that the diameter of a grape is 3 cm (in a spherical way), the ratio of the first example is (eq 1):

$r_{1} = \frac{3 cm}{1 mi*\frac{160934 cm}{1 mi}} = 1.86 \cdot 10^{-5}$

Now, the ratio of the second example is (eq 2):

$r_{2} = \frac{10^{-13} cm}{10^{-8} cm} = 1.00 \cdot 10^{-5}$

Since r₁ and r₂ are in the same order of magnitude (10⁻⁵), we can conclude that the given claim is reasonably accurate.

70 bags is the answer.
They add “They put 7 pieces of candy in each bag to throw you off”
To find the answer just divide 28 bags by 4 days to get how many bags they make in 1 day. Take that number “7” and multiply it by 10 days. The answer is then 70.
