Blue litmus paper turns red in the presence of an acid. Therefore, it can be assumed that the substance in the beaker is an acid.
Acids have a pH level of less than 7. Consequently, it can be assumed that the substance has a pH level less than 7.
Answer:
<em>At equilibrium, the rate of the forward, and the reverse reactions are equal.</em>
Explanation:
In an equilibrium chemical reaction, the rate of forward reaction, is equal to the rate of reverse reaction. Note that the reactions does not cease at equilibrium, but rather, the reactants are converted to product, at the same rate at which the product is also being converted into the reactants in the reaction. When chemical equilibrium is reached, a careful calculation of the value of equilibrium constant is approximately equal to 1.
NB: If the value of equilibrium constant is far far greater than 1, then the reaction will favors more of the forward reaction, and if far far less than 1, the reaction will favor more of the reverse reaction.
A three dimensional circular shape would be a sphere :)

copper
Explanation:
it's on the periodic table of elements
Answer:
Convention currents are found in the asthenosphere part present in the mantle of the Earth.
Explanation:
The Mantle is the middle layer of the earth surface extending up to 2900 kilometers.
Beneath the Mantle lies the core which contains molten rocks and materials called magma.
The materials are highly radioactive and immensely heated. These highly hot condition creates pressure on the middle layer (Mantle).
As a result, large convention currents are generated excessively
