What is an electronegativities?

Answers

Answer 1

Answer: - is a measure of the tendency of an atom to attract a bonding pair of electrons.The Pauling scale is the most commonly used. Florine, is the assigned value of 4.0, and range down to cesium and francium which are least electronegative at 0.7 .

A suitcase (mass m = 18 kg) is resting on the floor of an elevator. The part of the suitcase in contact with the floor measures 0.50 m × 0.15 m. The elevator is moving upward with an acceleration of magnitude 1.6 m/s2. What pressure (in excess of atmospheric pressure) is applied to the floor beneath the suitcase?

Answers

Answer:

P=2736 Pa

Explanation:

According to Newton we have that:

∑ $F=m*a\n$

A force is exerted by the elevator to the suitcase, according to 3th Newton's law an equal force but in the opposite direction will appeared on the suitcase, that is:

∑ $F=m*g+m*a=m*(g+a)$

$F=205.2N$

We know that the pressure is given by:

$P=(F)/(A)\nP=(205.2N)/((0.50m)*(0.15m))\nP=2736N/m^2=2736Pa$

If there are 50 grams of U-238 on day zero of radioactive decay, how much will there be after 4.5 billion years

Answers

We use the formula of the half-life to calculate for the remaining U-238 after 4.5 billion years. The formula is expressed as A = A₀ (1/2)^(t/h) where A is the final amount, A₀ is the initial amount of the substance, t is the time and h is the half-life of the substance wherein for U-238 h is equal to 4.47 billion years.

A = A₀ (1/2)^(t/h)
A = 50 (1/2)^(4.5 / 4.47)
A = 24.88 g
