What is the name of the substance created when zinc is heated with sulphur?
The substance created when zinc is heated with sulphur is zinc sulfide.
Is a brass screw a pure substance?
No, a brass screw is not a pure substance. Brass is an alloy made up of copper and zinc, so it is considered a mixture rather than a pure substance.
Is zinc hot or cold?
Zinc can be virtually any temperature as can nearly all substances. No substance in inherently hot or cold.
What transports zinc?
Zinc is primarily transported in the body bound to proteins such as metallothionein and albumin. It can also be taken up by cells bound to the zinc transporter proteins. In the bloodstream, zinc is mainly carried by albumin.
Is zinc a chemical property?
Zinc is not a property at all; it is a substance. Like all substances it has its own set of physical and chemical properties.
What is the name of the substance created when zinc is heated with sulphur?
The substance created when zinc is heated with sulphur is zinc sulfide.
What will be the color of zinc oxide with nitric acid?
Zinc nitrate is a white substance.
Is zinc a pure substance or a mixture?
Zinc is a pure substance because it consists of only one type of element, which is zinc.
How many substance can zinc be in?
There are at least theoretically an infinite number of possible zinc compounds.
Is zinc a pure substance?
Yes, zinc is a pure substance. It is an element with the chemical symbol Zn and atomic number 30.
Suppose that 273g of one substance listed zinc silver lead displaces 26ml of water What is the substance?
The substance is likely zinc. Zinc has a density close to 7.14 g/cm^3, so 273 g of zinc would displace about 38.2 ml of water (273 g ÷ 7.14 g/cm^3 = 38.2 cm^3 or ml). Since the displacement is 26 ml, it closely matches with the expected value for zinc, indicating that the substance is most likely zinc.
Why powdered zinc act more vigorously than metal zinc?
Powdered zinc has a greater surface area giving it a greater chance to react with a substance.
Is zinc an amphoteric substance?
No, zinc is not an amphoteric substance. Amphoteric substances have the ability to react as both an acid and a base, while zinc typically acts as a Lewis acid, accepting electron pairs in chemical reactions.
Is a brass screw a pure substance?
No, a brass screw is not a pure substance. Brass is an alloy made up of copper and zinc, so it is considered a mixture rather than a pure substance.
Is zinc hot or cold?
Zinc can be virtually any temperature as can nearly all substances. No substance in inherently hot or cold.
