Answer:

1.20x10⁻²⁰μL

Explanation:

1cm³ is equal to 1milliliter. As we must know, 1milliliter = 1000 microliters, 1000μL. To convert the 1.20x10⁻²³mL we need to use the conversion factor: 1mL = 1000μL.

The volume of tantalum in μL is:

1.20x10⁻²³mL * (1000μL /1L) = 1.20x10⁻²⁰μL

Which of the following statements is/are true regarding hydrogen bonds in water?
kap26 [50]

Answer

B,C,D,E

Explanation:

Hydrogen bonds in water forms a tetrahedral ( four sided structure) and not a six sided structure.

The hydrogen bonds are needed to be broken first when heat is applied to change from one state to another.It makes room for more heat to be applied than the required amount which signifies a higher latent heat of melting or vaporization and also a higher heat capacity .

Write a paragraph explaining the effect of surface area on the rate of reaction.
nexus9112 [7]
(For a bit of context I will use the reaction between HCl and Mg as an example)

The larger the surface area of the magnesium metal, the more particles are exposed to collide with the aqueous HCl particles to cause the reaction to occur. This increases the frequency per second of collisions, speeding up the rate of reaction.

The effect of a catalyst is to reduce the minimum collision energy which allows the reaction to happen. This does not increase the number of collisions per second, but increases the percentage of successful collisions, which consequently causes the rate of reaction to increase .

I have drawn diagrams showing the effect of surface area, but there isn't really a meaningful diagram that I know of to show the impact of a catalyst (at least not at GCSE level).

A car is held motionless off the ground by a hovering helicopter. If the car's mass is 1500kg, what is the force on the car due
bixtya [17]

<span>Force of the helicopter is equivalent to weight for this case. </span>Weight is calculated by multiplying the mass of the object and the acceleration. For this case, the acceleration would be the acceleration due to gravity which is equal to 9.81 m/s^2. We calculate as follows:<span>

W = mg 
<span>W = 1500 kg ( 9.81 m/s^2 )</span></span>

<span><span>W = 14715 N </span></span>
