To determine the mass of the iceberg, we simply multiply the density with the volume. Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. Remember that the units should be homogeneous. We calculate as follows:
mass = density x volume
mass = 0.92 g /cm^3 ( 9470 ft^3) ( 30.48 cm / 1 ft )^3 ( 1 kg / 1000 g ) = 265.55 kg
What ozone layer do we live in?
Answer: We live in the troposphere. There are 4 ozone layers: Troposphere, Stratosphere, mesosphere and atmosphere(of course)
The troposphere is the first layer<span> above the surface and contains half of the </span>Earth's atmosphere<span>. Weather occurs in this </span><span>lay</span>
Based on the effect of temperature on a reaction, a change in temperature affects the rate constant K.
Based on the Arrhenius equation, the y-intercept gives the value of ln A.
From the value of the slope, the value of Ea is 42.1 J/mol.
<h3>What is the effect of temperature on a reaction?</h3>
A change in the temperature of a reaction acts to increase the rate of reaction.
- Change in temperature has no effect on the ideal gas constant.
- Change in temperature has no effect on the activation energy.
- Change in temperature has no effect on the concentration of reactants.
- Change is temperature can either lower or increase the rate constant of a reaction.
- Change in temperature has no effect on the order of reaction.
According to the Arrhenius equation, the y-intercept gives the value of ln A.
From the graph; slope = -Ea/R
Ea = -slope/R
Where;
- Ea is activation energy
- R is molar gas constant = 8.314 J/K.mol
- Slope = -350 K
Ea = -(-350)/8.314
Ea = 42.1 J/mol

Answer:
Explanation:
Sn (Z = 50 )
Electronic configuration = [Kr] 4d¹⁰5s²5p²
= 1s²2s²p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p²
So , total number of electrons in d orbital = 10 + 10 = 20 .
This would go under the biology topic bUt I think I might be able to answer?
Neurotic cells of the nervous system send signals to the circulatory system for it to preform its proper functions. Especially since the nervous system works with sensory, I think this has something to do with wound and blood aiding but I could be wrong.
Sorry I couldn’t be a better help, but I hope this kinda gives you an idea
