chemical balance

Voorbeeldzinnen

1. The oxygen balance is calculated for the chemical reaction:
2. the substance contains chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than -200, or
3. Chemical products for industrial use — Determination of vapour pressure of solids and liquids within range from 10–3 to 1 Pa — Vapour pressure balance method.
4. The substance contains chemical groups associated with explosive properties which include oxygen and the calculated oxygen balance is less than - 200;
5. Consequently, measures have been taken to strike an appropriate balance between the desire to exploit all possible means to prevent drug precursors reaching illicit drug manufacturers and the commercial needs of the chemical industry and other operators.
6. The use of chemical nitrogen on dairy grassland has reduced by 37 % since 1999 and amounts to 128 kg N/ha in 2007. The OECD national nitrogen and phosphorus balances show for the period 1985 and 2002 a decline for the nitrogen balance from 46 to 22 kg N/ha and for the phosphorus balance from 15 to 12 kg P/ha.
