Answer:
D. Thermometer
Explanation:
The equipment used to measure the temperature of any reaction is the thermometer.
A thermometer is any device that has been specifically calibrated to measure the temperature values of reaction.
- Temperature is the degree of hotness or coldness of a body.
- Cold bodies have very low temperature.
- Hot bodies have high temperatures.
- There are different types of thermometers in use for various purposes.
Answer:
The honey would sink to the bottom
Explanation:
A simple interpretation of Archimedes' principle is that, in water, the bodys with density lower than that of water will float on top of the water (That is, density <1g/mL). In the other way, a body with density higher than that of water will sink to the bottom.
As density of honey is higher than density of water:
<h3>The honey would sink to the bottom</h3>
Answer:
2P4O10 + 2H2O → 2H3PO4
Balanced Equation → P4O10 + 6H2O → 4H3PO4
Tetraphosphorus Decaoxide + Water → Phosphoric Acid
Reaction Type → Synthesis
Answer: Natural gas is produced from onshore and offshore natural gas and oil wells and from coal beds.
Explanation:
The question is incomplete, the complete question is; Describe the preparation of 2.00 L of 0.108 M BaCl2 from BaCl2.2H2O
Answer:
See explanation
Explanation:
First we must know the molar mass of the compound = 244.3 g/mol
Now we must calculate the number of moles of BaCl2.2H2O in the solution.
number of moles = concentration * volume = 0.108 M * 2.00 L = 0.216 moles
Now the mass of solid that we need to take can be obtained from;
number of moles = mass/molar mass
mass = number of moles * molar mass
mass = 0.216 moles * 244.3 g/mol
Mass = 52.8 g
Hence, we must weigh 52.8 g of BaCl2.2H2O accurately in a balance and dissolve it in 2 L of water to give 0.108 M solution of BaCl2.2H2O.
