DanielleElmas [232]2 years ago

Answer:

O The heat absorbed in Trial 1 is about 3,347) greater than the heat absorbed in Trial 2

Explanation:

Using the formula as follows;

Q = m × c × ∆T

Where;

Q = amount of heat absorbed (J)

m = mass of substance (g)

c = specific heat of water = 4.18J/g°C

∆T = change in temperature (°C)

* For trial 1:

m = 30g

∆T = 40°C - 0°C = 40°C

Q = 30 × 4.18 × 40

Q = 5016J

* For trial 2:

m = 40g

∆T = 40°C - 30°C = 10°C

Q = 40 × 4.18 × 10

Q = 1672J

From the above results, it is clear that the amount of heat absorbed in trial 1 (5016J) is greater than that absorbed in trial 2(1672J) with a difference of 3344.

What is the pH difference of two samples if the concentration of [H+] ions is 1000-fold less in the second sample?
snow_tiger [21]
The correct answer is a. This is because the pH of a solution is defined as -log10(concentration of H+ ions). An inverse logarithmic scale such as this means that a solution with a lower concentration of H+ ions will have a higher pH than one with a higher concentration. Therefore we know that the pH of the second sample will be higher than the first.

Since the logarithmic scale has the base 10, a change by 1 on the scale is a consequence of multiplication/division of the H+ concentration by a factor of 10. As the scale is inverse, this means that a decrease of concentration by factor 1000 is equivalent to increasing the pH by (1000/10) = 3.

What part of the sun do we see from earth?
NISA [10]

Answer:

photosphere

Explanation:

photosphere

There are 3 main layers of the Sun that we can see. They are the photosphere, the chromosphere and the corona. Together they make up the "atmosphere" of the Sun. The part of the Sun that glows (and that we see with the naked eye) is called the photosphere
