What else can I help you with?
Why is graphite in pencil mixed with clay?
To make it harder. Pure graphite would be too soft for use as a writing pencil.
What gas would you get if you mixed hydrochloric acid and magnesium carbonate?
Carbon Dioxide
What would be the colour of the solution when copper oxide and dilute hydrochloric acids are mixed?
Blue
What gas would you get if you mixed hydrochloric acid with calcium?
Those compounds produce hydrogen (gas).
What gas would you make if you mixed hydrochloric acid with magnesium?
When hydrochloric acid is mixed with magnesium, hydrogen gas is produced along with magnesium chloride. This reaction can be represented by the chemical equation: 2HCl + Mg -> MgCl2 + H2.
When water and hydrochloric acid are mixed why does the pH differ when more acid is mixed?
because pH is the measure of how much acid it contains it would change if you added more
What salt would you get if you used calcium hydroxide and HCl?
You would get calcium chloride and water if you mixed calcium hydroxide and hydrochloric acid.
What gas would you get if you mixed hydrochloric acid and magnesium?
hydrogen gas.. and it also produces a salt Mg(s) + H2SO4(aq) ¾ ¾ ® Mg2+(aq) + SO42-(aq) + H2(g)
What would happen if acetic acid was mixed with hydrochloric acid?
When acetic acid is mixed with hydrochloric acid, an exothermic reaction would occur, leading to the formation of water and an acetate salt. The reaction would release heat and produce chloride ions as byproducts. The resulting mixture may have a lower pH than either of the original acids.
What would happen when you connect graphite to an electric circuit?
When graphite is connected to an electric circuit, it conducts electricity due to the presence of delocalized electrons in its structure. This allows the flow of electrons through the graphite, completing the circuit and enabling the transfer of electrical energy.
What would you get if you mixed copper with hydrochloric acid?
Mixing copper with hydrochloric acid would produce copper chloride and hydrogen gas. This reaction would dissolve the copper, forming a blue-green solution of copper chloride. The release of hydrogen gas could be observed as bubbles.
Where would you find graphite?
you would find graphite A.K.A black lead in pencils occasionally some paints
