Answer:
Disagree.
Explanation:
Nothing would remain. Everything on Earth is made up of atoms. The chair consists of only atoms. So, if you remove all of the atoms, nothing would be left! Hope this helps.
Common sense tells me that it is asthma cause i have it and yeah good luck
First we calculate the concentration of HCl:
Moles = mass / Mr
= 25 / 36.5
= 0.685 mol
Concentration = 0.685/1.5 = 0.457 mol / dm³
For a strong monoprotic acid, the concentration of hydrogen ions is equal to the acid concentration.
pH = -log[H+]
pH = -log(0.457)
= 0.34
A. False. If it is high tide in one place on Earth, the place exactly opposite to it will also have a <em>high</em> tide.
The gravitational attraction of the Moon and the inertia of the oceans cause <em>two tidal bulges </em>on opposite sides of the Earth.
B. True. Cassini used flybys of Venus, Earth and Jupiter as slingshots to reach Saturn.
C. True. The whole solar system moves around the galaxy.
D. True. If a planet’s gravity is not strong enough, the molecules in its atmosphere will have enough kinetic energy to escape into space.
E. False. The <em>mass of an object is constant</em>, but its <em>weight changes</em> according to the gravity of the planet.
F. False. To find the mass of an object, <em>divide</em> its weight by gravity.
or weight = mass × gravity
∴ <em>Mass = weight/gravity
</em>
Answer:
(a) 
(b)


(c) 
Explanation:
Hello,
(a) In this case, with the given formula we easily compute the mass of gold contained in the sovereign as shown below:

(b) Now, by knowing the density of gold and copper, 19.32 and 8.94 g/cm³ respectively, we compute each volume, by also knowing that the rest of the coin contains copper:


(c) Finally, the volume is computed by dividing the total mass over the total volume containing both gold and copper:
