Answer:

By finding the number of protons

Explanation:

Keep in mind when trying to find the number of electrons of a element, the number of electrons also equals the number of protons. In order to find the number of protons in the element simply find it's atomic number.

Example:

Find the number of electrons in the element iron.

Fe (Iron)

Fe's atomic number is 26

Protons/electrons = 26

Hope this helps.

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.

What would happen if our intestines were not coiled (twisted) inside our body?
grandymaker [24]

Answer:

If there is a change in the natural shape of the intestines, this can be known as a twisted bowel. A twist in the small intestine is referred to as a volvulus. Twists in the large intestine are known as a colonic volvulus. These abnormal twists or loops can cause an obstruction or other medical conditions which could be fatal. If signs of twisting bowel present, it is important to seek medical attention as quickly as possible.

suppose you use a pitcher to to estimate 1.25 qt of water ( experimental volume) . You later measured the volume more precisely
saul85 [17]

The percent error in the initial measurement would be 6.47%

<h3>Percent Error</h3>

Percent error in any measurement is mathematically given as:

                    absolute error/true measurement x 100%

In this case;

True measurement = 1.34 qt

Absolute Error = 1.34 - 1.25

                         = 0.09 qt

Percent error = 0.09/1.34 x 100%

                      = 6.47%

A container has the dimensions of 10cm x 80mm x 0.15m. The density of
vesna_86 [32]

Answer:

2.52kg

Explanation:

80mm = 8 cm

0.15m = 15 cm

volume of the container = 10m × 8cm × 15cm

= 1200 cubic centimetres

mass = density × volume

= 2.1 × 1200

= 2520g

2520/ 1000

= 2.52kilograms
