<u>Answer:</u> The number of neutrons in osmium is 114.

<u>Explanation:</u>

Atomic number is defined as the number of protons that are present in an atom. It is represented as 'Z'

Atomic number = Number of protons

Mass number is defined as the sum of number of protons and number of neutrons that are present in an atom. It is represented as 'A'

Mass number = Number of neutrons + Number of protons

We know that:

Atomic number of osmium = 76

Mass number of osmium = 190

Number of neutrons = 190 - 76 = 114

Hence, the number of neutrons in osmium is 114.

Answer:

Here's what I get  

Explanation:

The fatty acids form ester C-O bonds with the OH groups of glycerol and the phosphoric acid forms phosphate P-O bonds.

The phosphate also forms P-O ester linkages with the OH groups in other alcohols such as choline.

The structure below shows the phospholipid with two saturated C₈ fatty acids and the phosphate group.

If the freezing point of a soda is – 4.5 ºC and you leave it in your car overnight when the temperature dips to 25 ºF, will the
Sveta_85 [38]

Explanation:

We leave a soda in the car overnight and the temperature dips to 25 °F. To see if it will freeze we have to convert the °F to °C.

T(°C) = ( T(°F) - 32 ) *5/9

T(°C) = (25 - 32) *5/9

T(°C) = -3.9 °C

Since -3.9 °C is a temperature greater than the freezing point (-4.5 °C) the soda won't freeze.

Answer: The soda won't freeze.
