When the same amount of heat is added to cold sand and cold water, the temperature change of sand will be higher because of its lower specific heat capacity.

<h3>What is specific heat capacity?</h3>

Specific heat capacity is the quantity of heat required to raise a unit mass of a substance by 1 kelvin.

<h3>Specific heat capacity of water and sand</h3>

Water, c = 4,200 J/kg⁰C

Sand, c = 830 J/kg⁰C

Q = mcΔθ

where;

  • Δθ is temperature change
  • Q is quantity of heat added

Δθ = Q/mc

Thus, for an equal mass of water and sand, when the same amount of heat is added to cold sand and cold water, the temperature change of sand will be higher because of its lower specific heat capacity.

Which mineral leaves a green-black powder when rubbed against an unglazed porcelain plate
solong [7]

<u>Answer:</u>

Pyrite leaves behind a green-black streak when it is rubbed against an unglazed porcelain plate as a part of the streak test process.

<u>Explanation:</u>

Different minerals produce different coloured streaks when rubbed against a white ceramic or porcelain streak plate. This streak test is done to identify the mineral and distinguish the same from other minerals that look similar in colour and texture.

It must be ensured that the test is done on clean and fresh specimens of the mineral and that there must be no contaminants. Pyrite specimens are usually brass-yellow colour but it leaves a green-black streak when the streak test is done.

Draw the major product formed when the structure shown below undergoes substitution in ch3ch2oh with heat. (use a wavy bond (sin
muminat

Answer:

Explanation:

The missing image is attached below.

The objective of this question is to draw the major product formed from the diagram attached below.

From the diagram attached, we will see the reaction of a tertiary alkyl halide together with a weak nucleophile (ch3ch2oh) undergoing a nucleophilic substitution (SN₁) mechanism to yield a racemic mixture(i.e., compound that is not optically active but contains an equal amount of dextrorotatory and levorotatory stereoisomers) as a product.

amid [387]
<span>As mentioned, the isomerization of cyclopropane to propylene is a first-order process with a half-life of 19 min at 500°c. A first-order reaction kinetic rates means that the rate is constant throughout the reaction.

Thus, the time it takes for the partial pressure of cyclopropane to decrease from 1 atm to 0.125 atm at 500°c is </span><span>57 minutes.</span>

How do ethical concerns effect scientist research?
mario62 [17]

Answer:

Hi there!

Your answer is:

Ethical concerns dictate everything about scientific research. They determine what can be researched, who it can be researched on, how the data will be presented, how long the subjects can be researched, and more. To get a research study approved by the Institutional Review Board, you need to abide by strong ethical codes. In conclusion, a researchers ethical standings determines everything about their study.

Hope this helps
