Answer:
in parallel
Explanation:
All of the home equipment in the residence are linked in parallel.
Are domestic appliances linked in collection or parallel?parallel association
electric appliances are connected in a parallel arrangement in a house circuit because every appliance gets complete voltage as resistance in a parallel association is low.
Why are electrical appliances in our household no longer connected in collection?electric appliances are not linked in series because the cutting-edge can be the same thru all the home equipment connected but voltage increases if extra no. Of appliances are related. If the battery has low voltage than the full voltage it can short circuit.

A 3.5 kg iron shovel is left outside through the winter. The shovel, now orange with rust, is rediscovered in the spring. Its mass is 3.7 kg. How much oxygen combined with the iron?
Fe + O2 ⟶FeO2⟶FeO2,As we can see our compound is FeO2FeO2 which is a simple combination with the same stoichiometry, so we will just do a subtract operation : 3.7 kg - 3.5 kg $= 0.2 \ \text{kg} \Rightarrow 0.2\color{#4257b2}{0} $ kgkg (respecting significant figures rule).
What does iron and oxygen together mean?Rust is the result of an iron and oxygen interaction together:It's an ionic since it is made up of the a metal and something that is not a metal.
Iron may rust even without water?Without water, rust cannot develop.Iron pipes frequently rust on the inside due to water vapor condensation on the metal.Moisture facilitates the electrolyte required for the reaction iron take place, which expedites the rusting process.

Answer:
a) HCl
Explanation:
As we know, that HCl or Hydrogen Chloride is a diatomic compound. It is formed due to the Chemical reaction of Hydrogen and Chlorine. As both Hydrogen and Chlorine have valencies of 1, the Net Valency of the Compound HCl is 1 itself. This separates it from the rest of the compounds. The rest of the compounds need to have more than 2 atoms of each kind and have different valencies too.

what occurs along a convergent plate boundary ?
Answer:
Two plates pull towards each other
Explanation:
Along a convergent plate boundary, two plates moves towards each other as the move in the same direction.
This results in different forms of plate interactions depending on the plate types.
At an ocean - ocean and continental - ocean convergent front, subduction of the oceanic plate occurs. This is because the oceanic plate below is denser than the asthenosphere. At a continental - continental convergent front, the continental crust is pulls upward and build up as a mountain. The subduction produces trenches and some volcanic islands.Answer:
What happens along a convergent plate boundary?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. ... The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary

Explanation:
En un vaso se han puesto 250 g de alcohol junto con 2 g de yodo, que se disuelven completamente. Calcular la concentración de la disolución en % en masa.
The translation of the question is
250 g of alcohol have been put in a glass together with 2 g of iodine, which dissolve completely. Calculate the concentration of the solution in% by mass?
Answer:
The %mass by mass of the given solution is 0.794%
Explanation:
We are given
Mass of solute(Iodine) = 2g
Mass of the solvent (Alcohol) = 250g
Since the Iodine dissolves completely in Alcohol
Total mass of the solution = 250 + 2 = 252g
the formula of concentration of the solution in % by Mass is given by
%[tex]\frac{w}{W} = \frac{Mass of the solute*100}{Total mass of the solution}[/tex]
%w/W = [tex]\frac{2*100}{252}[/tex]
= 0.794%
Therefore the %mass by mass of the given solution is 0.794%
