Answer:

b. Extrinsic motivational statement

Explanation:

This is an example of a extrinsic motivational statement. In this example, Sheri's motivation for getting good grades is her parents. She wants to make her parents proud, and she believes that this is what her parents expect of her. None of the motivations are internal. Therefore, Sheri's motivation is an extrinsic one.

Describe where a hydrogen bond can form among water molecules.
stiv31 [10]

Answer:

                 In water hydrogen bonding formed between partially negative oxygen and partially positive hydrogen atoms.

Explanation:

                  Hydrogen bond is a partially electrostatic attraction between hydrogen (H), which is bonded to a more electronegative atom such as nitrogen (N), oxygen (O) or fluorine (F), and another adjacent atom bearing a lone pair of electrons.

                   In water molecule hydrogen and oxygen have difference in electronegativity, due to which dipoles are form. One is partial positive on hydrogen atom and other is partial negative on oxygen atom. The electrostatic attraction occur between two oppositely charged poles which is known as hydrogen bonding.

Give the volume indicated. Be sure to include all significant figures.
miskamm [114]

Answer: -

71

Explanation: -

From the diagram, we see that volume goes from 70 to 75 in 5 markings.

Each marking is for 1.

It is the most accuracy possible as there is no smaller marking.

Significant figures expresses the required amount of accuracy.

Thus the volume indicated from the diagram is 71 .

A serving of soup contains 5.0 g of fat, 20.0 g of carbohydrates, and 3.0 g of protein. Determine how many kilocalories (kcal) a
marta [7]

<u>Answer:</u> The amount of kilocalories contained in the given serving of soup is 0.137 kCal

<u>Explanation:</u>

<u>As per the USDA:</u>

Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.

We are given

Mass of fat in the soup serving = 5.0 g

Mass of carbohydrates in the soup serving = 20.0 g

Mass of protein in the soup serving = 3.0 g

Conversion factor used:  1 kCal = 1000 Cal

Applying unitary method:

  • <u>For Fat:</u>

1 gram of fat provides 9 calories

So, 5.0 gram of fat will provide = \frac{9}{1}\times 5.0=45Cal=0.045kCal

  • <u>For Carbohydrates:</u>

1 gram of carbohydrates provides 4 calories

So, 20.0 gram of carbohydrates will provide =\frac{4}{1}\times 20.0=80Cal=0.080kCal

  • <u>For Proteins:</u>

1 gram of proteins provides 4 calories

So, 3.0 gram of fat will provide = \frac{4}{1}\times 3=12Cal=0.012kCal

Total kilocalories per serving = [0.045 + 0.080 + 0.012] kCal = 0.137 kCal

Hence, the amount of kilocalories contained in the given serving of soup is 0.137 kCal

Can a solution of Sn(NO3)2 be stored in an aluminum container?
givi [52]
I believe a solution of Sn(NO3)2 can not be stored in an aluminium container because Aluminium is higher in the reactivity series compared to Tin (Sn). Therefore, Aluminium is more reactive than Tin and hence aluminium will displace Tin from its salt forming Aluminium nitrate and Tin metal. Thus storing Tin nitrate in an aluminium container will cause the "eating away' of the container.
