    When any fluid reacts with the initial composition of a mineral or a rock, an addition, exchange or replacement of ions takes place, i.e initial composition is altered, defined as chemical ....

  • Waiting for answer What pressure (in torr) is exerted by 10.0 g of O2 in a 2.50...

    The pressure exercited by the gas will be ##"2300 torr"##. So, you know that you have a certain amount of gas, 10.0 g to be exact, in a 2.5-L container at ##27^@"C"##. You can use the equation to solve for the pressure in atm, then use a simple conversion factor to go from atm to torr. The numb...

  • Waiting for answer Suppose three nucleotides are inserted into a gene. Will thi...

    No, because 3 genes are a complete codon. A frameshift is a mutation by insertion or deletion of a number of genes that is NOT divisible by 3.

  • Waiting for answer What rule is used to join the free nucleotides to the expose...

    The base-pairing rule describes how the nitrogen bases pair with one another. For , the base-pairing rule states that adenine always pairs with thymine, and cytosine always pairs wit...

  • Waiting for answer How does your calculated empirical formula (Mg3O2) of magnes...

    The correct formula for magnesium oxide is MgO. This is because Mg forms a +2 ion and O forms a -2 ion. The ions will combine to produce a compound which is neutral (no charge). A common chemistry experiment many students carry out can determine the empirical formula by allowing magnesium metal t...

  • Waiting for answer What is a hotspot and where are they located?

    Hotspots are thermal plumes within the Earth's mantle. They are located in various parts of the planet. The most famous is beneath the island of Hawaii. The chain of volcanic islands that make up the Hawaiian Islands were formed due to the drifting of the Pacific Plate over the hotspot. The big I...

  • Waiting for answer How can transverse waves be produced on a rope?

    You can produce on a rope by moving one end of the rope up and down. You create a transverse wave by inducing in the particles that make up a respective medium a motion perpendicular to the direction of propagation. In your case, the medium will be the rope. When you move the rope up and down,...
