He do not catch fire like hydrogen. The correct option is c. Helium and hydrogen can be used in balloons but it is safer to use helium as it can help in keeping the balloon afloat and cause no harm . He is a inert element. Hydrogen is lighter than air but it is flammable and as oxygen is present in the air, so the risk of explosion .
Helium is used in balloons in place of hydrogen because it is a incombustible b lighter than hydrogen c radioactive d more abundant than hydrogen.
Helium gas is heavier than hydrogen gas , . Helium and hydrogen can be used in balloons but it is safer to use helium as it can help in keeping the balloon afloat and cause no harm . Helium is used in balloons because hydrogen is dangerous and causes severe problems like it escapes into the upper atmosphere and depletes ozone layer by . This is because helium is less dense. Helium gas is lighter than air, therefore, a helium balloon rises, it is known as a noble gas and is therefore not reactive. The correct option is c. Helium is used in balloons in place of hydrogen because it is a incombustible b lighter than hydrogen c radioactive d more abundant than hydrogen. Helium is used in balloons instead hydrogen as it is a highly combustible gas and if the balloon brusts it may cause damage to our skin or cause burns in our . Helium is the second element on the periodic table. Hydrogen is also lighter than air . He do not catch fire like hydrogen. Hydrogen is lighter than air but it is flammable and as oxygen is present in the air, so the risk of explosion . Hydrogen was originally used to fill balloons but it is a highly reactive gas.)
Helium is the second element on the periodic table. He is a inert element. The correct option is c. Hydrogen is also lighter than air . Because helium is lighter that air, a helium balloon rises, just as an air bubble rises in more dense water.
Helium is used in balloons because hydrogen is dangerous and causes severe problems like it escapes into the upper atmosphere and depletes ozone layer by .
