heat required: 169452 Joules

  • use the formula, Q = mcΔT

<u />

<u>Q is heat required, m is mass in kg, c is s.h.c , ΔT is change in temperature</u>

  • Here, the units of s.p.c and mass matches, in grams
  • if did not match, we have to convert into specific unit.

↪ Q = 1500 * 4.184 * (52-25)

↪ Q = 169452 J

  • Mass=1500g=m
  • ∆T=52-25=27°C
  • Specific heat capacity=c=4.184J/g°C

Apply thermodynamics

\\ \rm\rightarrowtail Q=mc\delta T

  • Q is heat

\\ \rm\rightarrowtail Q=1500(4.184)(27)

\\ \rm\rightarrowtail Q=169452J

Based on the information in the table, which of the following arranges the bonds in order of decreasing polarity?
patriot [66]

Polarity is the chemical property based on the electric charge and orientation of the poles. Al−O>H−Br>As−S is arranged in decreasing order of polarity. Thus, option d is correct.

<h3>What is polarity?</h3>

Polarity is a chemical property of the distribution of the electrical charges over their respective atom in the molecule joined by the bonds. The relation between the polarity and the difference in electronegativity is directly proportional.

The electronegativity difference between the elements are:

  • Al−O = 1.8
  • H−Br = 0.8
  • As−S = 0.4

As the electronegativity difference between Al−O = 1.8 is the highest it will have the highest polarity followed by H−Br = 0.8, and As−S = 0.4, with the lowest polarity.

Therefore, option D. Al−O>H−Br>As−S is arranged in decreasing order of polarity.

Two substances, A and Z, are to be identified. Substance A can not be broken down by a chemical change. Substance Z can be broke
I am Lyosha [343]
The answer is 3). This is because elements are the simplest form of a substance, and cannot be broken down any further. Compounds on the other hand are much more complex than elements and can be broken down INTO elements. For example, Na, sodium, is an element and cannot be broken down further. H2O, water, is a compound and can be broken down into Hydrogen and Oxygen.

Answer:

Early-warning systems are essential in the case of hurricanes, severe thunderstorms, tornadoes, tsunamis, and volcanoes. All of these can wreak havoc! Let’s take a look at how meteorologists forecast these events and how early-warning systems can help us protect ourselves if we are in their paths.

A flask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is atta
Rashid [163]
Following the Law of Conservation of Mass, you simply add the mass of both substances. Thus, 160 grams + 40 grams = 200 grams. So, even if initially, they are in liquid and solid form, they would still have the same mass even if they change phases, owing to that they are in a closed space.
