What is an organism containing a new gene?
Transgenic - Refers to an organism containing one or more deliberately inserted genes from another species. Examples are bacteria containing the gene for human insulin and plants that contain the gene for a naturally occurring insecticide.
What element makes a glowing splinter burst into flame when inserted into a test tube containing that element?
The element that makes a glowing splinter burst into flame when inserted into a test tube containing it is oxygen. Oxygen is a highly reactive gas that supports the combustion process, causing the wood splinter to ignite in the presence of a flame.
In the single replacement reaction between zinc and HCI what reaction resulted from inserting the lit splint into the test tube mouth?
When a lit splint is inserted into the mouth of a test tube containing hydrogen gas produced from the reaction between zinc and hydrochloric acid (HCl), a "pop" sound is heard. This sound indicates the presence of hydrogen gas, which is flammable. The reaction is represented by the equation: Zn + 2HCl → ZnCl₂ + H₂. The hydrogen gas ignites, producing the characteristic noise.
What is the conclusion of the properties of gas in a beaker based on the behavior of the burning splint?
When a burning splint is inserted into a beaker containing gas, its behavior indicates the nature of the gas present. If the splint extinguishes, the gas may be inert or lacking in oxygen. If the splint reignites or burns more brightly, it suggests that the gas is rich in oxygen or a flammable substance like hydrogen. Thus, the splint's reaction helps identify the gas's properties related to combustion.
How do you determine whether a gas given off during a chemical reaction is oxygen or hydrogen?
One way to determine whether a gas given off during a chemical reaction is oxygen or hydrogen is by performing a gas test. For example, the gas test for oxygen involves relighting a glowing splint when inserted into the gas. If the splint reignites, then the gas is oxygen. The gas test for hydrogen involves holding a lit match near the gas, and if a "pop" sound is heard, then the gas is hydrogen.
In a tube which gas 'pops' when a burning splint is inserted?
hydrogen

In the test tube which gas 'pops' when a burning splint is inserted?
Oxygen gas will "pop" when a burning splint is inserted into a test tube, due to the rapid combustion reaction that occurs between the oxygen and the flammable material on the splint. This reaction creates a small explosion sound known as a "pop".
In the single replacement reaction between zinc and HCI what reaction resulted from inserting the lit splint into the test tube mouth?
When a lit splint is inserted into the mouth of a test tube containing hydrogen gas produced from the reaction between zinc and hydrochloric acid (HCl), a "pop" sound is heard. This sound indicates the presence of hydrogen gas, which is flammable. The reaction is represented by the equation: Zn + 2HCl → ZnCl₂ + H₂. The hydrogen gas ignites, producing the characteristic noise.
What would happen if you hold a burning stick under hydrogen gas?
If anything burning is inserted into, or placed around a mass of Hydrogen gas, it will ignite the Hydrogen, causing it to "explode". The resulting explosion is very hot, and if done with too much Hydrogen gas, can be dangerous. Exercise caution when preforming this.
What procedure is involved in intravenous rehydration?
Sterile water solutions containing small amounts of salt or sugar, are injected into the body through a tube attached to a needle which is inserted into a vein.
What are coin envelopes used for?
The purpose of coin envelopes are for containing currency like coins when being mailed or exchanged. Because these envelopes are multipurpose, other small items can also be inserted in them.
What will happen when a inverted test tube is inserted into a measuring cylinder containing water?
As the inverted test tube is inserted into the measuring cylinder containing water, the water will rise up into the test tube due to atmospheric pressure. The level of water inside the test tube will stabilize at a certain height once the pressure inside and outside are balanced. This can be used to measure the volume of the test tube.
How did ling yao become greed?
In very much the same way as Bradley became Wrath: he had a Philosopher's Stone containing Father's 'greed' inserted into his bloodstream. He accepted it willingly in order to gain immortality.
How do you test if something is hydrogen or oxygen?
To test for hydrogen, you can use a glowing splint test: hydrogen will create a squeaky pop sound when a lit splint is inserted into a sample. For oxygen, the gas relights a glowing splint. Both gases can also be tested using chemical reaction tests or specialized equipment like gas detectors.
Will pure hydrogen give the same result when burning splinter inserted on the mouth of the test tube?
When burning hydrogen at the mouth of a test tube, it will produce a squeaky pop sound due to the rapid combustion of hydrogen gas. This reaction occurs because hydrogen easily reacts with oxygen in the air to form water vapor, releasing energy in the process. The splinter would likely catch fire and burn more vigorously due to the presence of hydrogen gas in the test tube.
