How do you think you can use the calorimeter to compare the specific heat capacities of a substance?

Answers

Answer 1
Answer:

Calorimeter is used for calculating specific heat capacities of a substance.

We can use the calorimeter in order to compare the specific heat capacities of a substance because calorimeter is a device which is used for measuring the heat produced during a mechanical, electrical or chemical reaction. This device has the ability to calculate the heat capacity of materials.

The heat released from the sample is absorbed by the water, which results in an increase in temperature. This calorimeter detect this increase in temperature and provides us information so we can conclude that calorimeter is used for calculating specific heat capacities of a substance.

Answers

Answer:

45

Explanation:

There are 12 Carbons

There are 22 Hydrogens

There are 11 Oxygens.

I think the answer is either 0 or 45. But the wording is very sloppy. It is not really atoms that are present. There are ions.

Go with 45 but hold your nose when writing your answer.

What characteristic is important for plants found in saltwater wetlands?

Answers

Answer : Salinity tolerance

Explanation :

The important characteristics for the plants which are found in salt water wet lands is salinity tolerance.

Salinity tolerance is the salt tolerance of crops in the wet lands which gives maximum salt level that a crop can tolerate without losing its productivity.

Although it may get affected negatively at higher levels of exposure. The salt level is often measured as the soil salinity or else the salinity of the irrigated water.

I think that the ants would prefer honey and maple syrup - as they're full of sugars that the ants can convert to energy.

I think that the ants would also locate the source of the food very fast and that they would go there directly -as if they were telling each other where the food is. And it is true, the ants can tell the other ants to follow them in the source of food, similarly to bees.

An aluminum sample has a mass of 80.1 g and a density of 2.70g/cm3 . According to the date to what number of significant figures should the calculate volume of the aluminum sample be expressed?

Answers

80.1 g* (1 cm^(3)/ 2.70 g)= 29.666666... cm^(3).

The calculated volume should have 3 significant figures, so the final answer is 2.97*10^(1) cm^(3)

Hope this helps~
3 Sig figs because both measurements have three sig figs. In a lab setting, you would round to your least precise measurement. So its useless to use a meter stick and a high precision scale to take measurement because you have to use the amount of Sig figs for your least precise tool
