Answer:
Carbon and oxygen are similar in a few ways. They are both elements, which are the fundamental building blocks of all matter. This means that they both have protons and electrons. They also both have neutrons
This is a biology question not a chemistry question. But these are all types of cells related to different cell division techniques. does that help?
Answer:
All electric heaters make use of one or more of the fundamental heat transfer mechanisms – namely convection, conduction, or radiation.
For regular...
Conduction is heat transfer by direct contact, like frying an egg. Convection is heat transfer by the movement of gases or liquids, like most home furnaces, clothes dryers, or car heaters. Radiation is the transfer of heat in waves through space, like the sun or a fire.
The question is incomplete, the complete question is:
Standardization of a Borax solution (Na2B4O7). A student titrates a 20.00 mL sample of an aqueous borax solution with 1.044 M H2SO4. It takes 2.63 mL of acid to reach the equivalence point. Knowing it takes 1 H2SO4 to neutralize 2 Na2B4O7, what was the concentration of this Borax solution?
<u>Answer: </u>The concentration of borax solution is 0.069 M.
<u>Explanation:</u>
To calculate the concentration of borax solution, the formula used is:
....(1)
where,
are the n-factor, concentration and volume of sulfuric acid
are the n-factor, concentration and volume of borax solution.
We are given:
Putting values in equation 1, we get:
Hence, the concentration of borax solution is 0.069 M.
