if a:b =2:3and b:c=6:10,find a:c.
Answer:
4:10
Explanation:
a:b
2:3
6:10
b:c
The common ratio is b
The lcm of 3 and 6 is 6.
Multiply the first ratio by 2 and the second one by 1
a:b:c
4:6:10
hence a:c = 4:10

how to find molar mass
Answer:
Multiply the element's atomic mass by the number of atoms of that element in the compound. This will give you the relative amount that each element contributes to the compound. For hydrogen chloride, HCl, the molar mass of each element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.

Explanation:
which of the following acts as a catalyst in catalytic converters?
A. Wood
B. Metal
C. Water
D. Gas
Answer:
B. Metal
Explanation:
The catalyst used in the converter is mostly a precious metal such as platinum, palladium and rhodium. Platinum is used as a reduction catalyst and as an oxidation catalyst. Although platinum is a very active catalyst and widely used, it is very expensive and not suitable for all applications.

A tower built of Iron is 500 meter tall. What is the change in height (m) if it is exposed to 25 0 Celsius during summer and at 1.00 Celsius during winter. α iron = 1.2 x 10-5/ Celsius
Answer:
-0.144 m
Explanation:
From the question,
α = Δh/(h₁Δt).................... Equation 1
Where α = coefficient of linear expansivity of iron, Δh = change in height, h₁ = initial height, Δt = change in temperature.
make Δh the subject of the equation
Δh = α(h₁Δt)..................... Equation 2
Given: α = 1.2×10⁻⁵/°C, h₁ = 500 m,
Δt = (t₂-t₁) Where t₂ and t₁ = Final and initial temperature respectively.
Δt = (1-25) = -24 °C
Substitute these values into equation 2
Δh = 1.2×10⁻⁵[500×(-24)]
Δh = 1.2×10⁻⁵(-12000)
Δh = -0.144 m
Which of the following objects would take you the greatest amount of force to accelerate?
Complete question is;
Which of the following object would take you the greatest amount of force to accelerate.
A) a soccer ball with a mass of 0.5 kg
B) a refrigerator with a mass of 200 kg, C) a bike with a mass of 25 kg
D) a car with a mass of 5,000 kg,
Answer:
D) a car with a mass of 5,000 kg
Explanation:
Formula for force is;
F = ma
Where;
F is force
m is mass
a is acceleration
Now, Force is directly proportional to the acceleration and mass.
Thus, the higher the mass, the greater the force.
Thus, the object that will require the most force is the one that has the highest mass.
Looking at the options, the one with the highest mass is option D.

How many moles of O2will be produced from 6.2 moles of water?
Answer:
I hope This will help you....and please mark me as Brilliant
Explanation:
The formula, H2O tels us that there are the same number of moles of Oxygen as there are of water. The (understood )molecular coefficient of H2O is 1. The (understood ) coefficient of O in the formula is also 1. The number of moles of oxygen is the same as the number of moles of water. This is moles of oxygen atoms. If the question wants moles of oxygen gas, O2, then it will be half as many I think that is what they want, so I would answer 3.1 moles of O2.
WHAT ARE SOME POSSIBLE CONSEQUENCES IF A HUMAN BODY DOES NOT MAINTAIN
HOMEOSTASIS
Answer: If homeostasis is disrupted, it must be controlled or a disease/disorder may result.
Explanation: What happens if there's disruption? Your body systems work together to maintain balance. If that balance is shifted or disrupted and homeostasis is not maintained, the results may not allow normal functioning of the organism.

Answer:
Water is a human necessity. Therefore, it is one of the first things a human settlement would need to have. A community cannot thrive without a water source.
Answer:
Water is a basic need that is more than a necessity, humans can't survive without water for more than a period of three days, And thus having water as available, creates a tendency among humans as humans like to get everything at ease so they tend to settle near the water bodies if possible.

If you get a root canal or any other potentially painful procedure done at the dentist's office, he or she will probably inject your gums with a local anesthetic to "numb the pain." Neurons that trigger pain are called nociceptors. They trigger pain in order to alert the body to potentially dangerous stimuli. Most local anesthetics hinder the activity of all local neurons, not just nociceptors, so pain is not the only sensation that goes away temporarily. Because all feeling is gone, you can end up drooling on yourself without knowing it.
Considering this information about local anesthestics, which of the following statements best demonstrates that science is an ongoing process that changes in response to new information and discoveries?
A. There are a variety of local anesthetics being used today, including lidocaine, prilocaine, and mepivacaine.
B. Sir Charles Sherrington, who discovered nociceptors, wrote a book about the nervous system that helped show its role in allowing organisms to adapt to their environments.
C. Unlike a local anesthetic, a general anesthetic causes a person to lose consciousness rather than sensation in one area.
D. Scientists have discovered a way to use a compound found in hot peppers, capsaicin, along with an anesthetic in order to block nociceptors only.
